Fusion Future: A New Era of Energy
summary
Commonwealth Fusion Systems lays out concrete milestones: build SPARC, a 70%‑scale prototype that’s predicted to produce 10x net gain prediction and run within about two years; follow with a 400 MW commercial ARC plant sited with a utility partner. Key tools are superconducting high‑field magnets made from recently commercialized materials, factory production lines adapted from auto and shipbuilding, and cryogenics at ~100 million °C plasma temperatures; current program size is ~1,000 people and $2 billion, with on‑site SPARC assembly already underway.
